I have same with RV340W - and during these moments wifi speed is 10~15Mb/s never more than this.
newest firmware installed Firmware 1.0.02.16
Does anybody know how to resolve?
thank you,

yet to upgrade, and the problem is still continuing.
Just curious, did you turn on other special feature?

Hi John Tsang.
please clarify what do you mean "did you turn on other special feature" ?

AMPDU Aggregation:
The purpose of AMPDU is to improve data transmission by aggregating or grouping together several MPDU blocks. Because of the technical background effects, the A-MPDU option offers a few advantages and disadvantages. There are a few key takeaways from this technology.
1. AMPDU is less efficient in terms of process and speed by itself.
2. AMPDU improves overall network performance by reducing overhead transmitted.
3. AMPDU improves error checking capability because of its additional Block Acknowledgement feature.
based on this in the manual (Wi-Fi > Basic Settings > WMM):
To prioritize and queue the traffic according to the Access Category (AC), check Enable
to enable the Wireless Multimedia Extensions (WME). Enabling WME may result in
more efficient throughput, but higher error rates within a noisy Radio Frequency (RF)
environment.
and this: (Wi-Fi > Advanced Settings > 2.4G and 5G):
(Optional) Check the Enable check box to enable WMM No Acknowledgement. The Wi-Fi Multimedia (WMM) option enables the Quality of Service (QoS) function that is used for multimedia applications such as VoIP and video. This allows the network packets of the multimedia application to have priority over regular data network packets, hence allowing multimedia applications to run smoother and with fewer errors. This feature results in more efficient throughput but with higher error rates.
I disabled WMM on my SSID, and the ampdu_dbg messages have stopped. I assume that the router was trying to aggregate/queue traffic which produced this error. I didn't try it, but I think you could leave WMM enabled, and check the box in 2.4G and 5G WMM No Acknowledgement and that might suppress the warnings, but the errors would still happen, you just would not see warning messages in the log. However, I did not test this, and would rather the router just not try to prioritize/aggregate multimedia traffic since I do have some time-sensitive traffic that I do not want de-prioritized. I am using firmware 1.0.03.16.
01-04-2021 04:51 AM
I did not have the option to disable WMM, it was greyed out. I turn on the No-acknowledgement and the log events went away.
